After a Redis outage, data can be restored using the following methods:

Try restarting the Redis service to see if data can be recovered. Congratulations if the Redis service can be restarted without data loss, as data has been successfully recovered.
Recovery with AOF files: If Redis is configured with AOF persistence, data recovery can be done using the AOF file. After a Redis crash, data can be restored by reloading the AOF file back into Redis.
Recovery using RDB file: If Redis is using RDB persistence, data can be restored using the RDB file. After a Redis crash, data can be recovered by reloading the RDB file into Redis.
Data recovery using Redis Sentinel or Redis Cluster: If Redis is set up to use Sentinel or Cluster for data backup and failover, these mechanisms can be utilized for data recovery.
Manual data recovery may be necessary if the methods mentioned above do not work. In such cases, recovering data backups or reimporting data may be required.

In general, the best approach for recovering data after a Redis outage is to have a backup of the data and a disaster recovery plan in place beforehand, so that data can be quickly restored in the event of an outage.
